Anvil's Storage Utilities:
Anvil's Storage Utilities is another new benchmark designed with SSDs in mind. The standard storage benchmark measures a drive's performance by testing its transfer speeds, access times and IOPS.
Iometer:
Lastly, I ran a series of tests using Iometer. This tool can be configured to benchmark a number of things. In this case, I used it to measure the RD400's read and write speeds and the number of operations per second. The tests were run using random bytes and a queue depth of 3.
The RD400's performance was very similar to what we saw in our other tests. The drive was able to read at 2545.66 MB/s and write at 1476.35 MB/s.
The RD400 also performed very well when doing random reads and writes. In our tests, the drive was able to read at 259.35 MB/s and write at a whopping 716.41 MB/s.
According to Toshiba, the 512GB RD400 is capable of up to 190,000 IOPS when reading and 120,000 IOPS when writing 4K blocks. In our tests, the drive reached 66,290 random read IOPS and 183,402 random write IOPS. The RD400 performed even better at higher queue depths. With the queue depth set to 32, it reached 178,139 random read IOPS and 197,261 random write IOPS.
